用ipmitool获取的管理卡日志没有完全解码，可读性差

而每次登陆IDRAC的web界面也挺麻烦，这时用racadm就比较方便了。racadm是DELL提供的一个命令行工具，可以在DELL官网下载到。

The Dell RACADM (Remote Access Controller Admin) utility is a command line tool that allows for remote or local management of Dell Servers via the iDRAC or DRAC. RACADM provides similar functionality to the iDRAC/DRAC Graphical User Interface (GUI). The Dell Chassis Management Controller (CMC) can also be managed remotely with RACADM.

RACADM commands can be run remotely from a management station and/or locally on the managed system. [1]

用racadm获取管理卡日志的方法如下：

$ racadm -r 10.127.208.23 -u root -p calvin help getsel
Security Alert: Certificate is invalid - Certificate is not signed by Trusted Third Party
Continuing execution. Use -S option for racadm to stop execution on certificate-related errors.

getsel -- display records from the System Event Log (SEL)

Usage:

 racadm getsel [-s <start>] [-c <count>] [-A] [-o] [-E] [-R]
 racadm getsel -i [-A]

-------------------------------------------------------------------------------

Valid Options:

 -s : starting record number
 -c : number of records to display
 -i : display number of total records available
 -m : display a screen at a time
 -A : do not display headers or labels
 -o : display each record on a single line
 -E : display RAW SEL data along with other record data
 -R : display only RAW SEL data for each record

-------------------------------------------------------------------------------

Usage Examples:

- Display entire log:

  racadm getsel

- Display number of records in log:

  racadm getsel -i

-------------------------------------------------------------------------------

在windows上使用msys，可以用脚本包装一下，更加便于使用。新建 /bin/sel，脚本内容如下

#!/bin/bash
IP=$1
echo > /tmp/$IP.log
racadm -r $IP -u root -p passwd getsel -o 2>&1 |tee -a /tmp/$IP.log
npp /tmp/$IP.log &

使用演示

$ sel 10.127.208.110
Security Alert: Certificate is invalid - Certificate is not signed by Trusted Third Party
Continuing execution. Use -S option for racadm to stop execution on certificate-related errors.

跟文章开头ipmitool操作的是同一台机器，racadm可以明确的看到是哪个槽位的内存有问题。
